Toney vs Barkley Floyd vs Gatti Saad vs Qawi I and II Chavez vs Rosario Duran vs Moore Calzaghe vs Lacy Hearns vs Randy Shields (basically a mini-version of Holmes vs Cobb) Pac vs Margarito Leonard vs Mayweather Sr.
Zelenoff is that nutcase who records himself sucker punching random people and then adds them as wins to his imaginary record. He trolled Deontay Wilder and made comments about his sick daughter, so Wilder smacked him around the gym. He was sparring with Floyd Sr, left the ring when Floyd decided to throw a couple punches, and then tried to attack Floyd from behind. Kim Kardashian also has a restraining order on him. I have to admit, I find him rather fascinating from a psychological standpoint. He is a special kind of crazy.
